Note:
(1) If the quantity you ordered is less than 10 or far more than 10, the sales price is different, Pleas contact us.
(2) Delivery time: We have a small amount of commonly used LD. When the quantity is large, it needs to be re-produced, generally 1 to 3 weeks, different models have different delivery cycles.
